 <h3>Enhanced vxStats device support</h3>
 
 <p>Incorporated various changes to the vxStats device support by Andy Foster
-that have been in use at APS for over a year. This version adds the ability to
-see absolute memory use in addition to the percentage figures available before,
-and also gives information on the number of file desciptors in use. These new
-figures use the longin record type, thus a new device support entry is provided
-in base.dbd to enable it. See the comments in
-<tt>src/dev/vxStatsDev/devVXStats.c</tt> for more detail on the new facilities
-and an example database.</p>

+<p>The CA client library's disconnected channel search message minimum period
